Good point. Just they spent their time trying to make it work thinking they could, as they saw it as the way forward. Put all their eggs into 1 basket. All their wings were built around the concept of it working. So after it failed I believe they chalked this season off.

Rosberg won near the start of the calendar. So maybe had they concentrated on upgrading the front wing etc not the DDRS, the car would of been more competitive during the season.
